Definitions

  • the present invention relates to a method of protecting organic material from the damage which can be caused by daylight (“visible light”) and, especially, by artificial light.
  • Organic material for example pharmaceuticals or, especially, organic material from the foodstuffs sector, for example vegetables, fruit and meat, contains organic substances that are sensitive to light irradiation, especially in the short-wave region of daylight (up to 500 nm) and in the UV region.
  • the spectra of daylight and artificial light are different.
  • the proportion of UV between 250 and 400 nm is smaller than that in daylight, but the proportion of light with extinction between 400 and 500 nm, with a maximum at about 480 nm (blue region), is significantly greater than in the case of daylight.
  • Vitamin B2 which is known to be very sensitive to UV light as well as to daylight up to 500 nm.
  • Vitamin B2 also known as riboflavin, is present in high concentrations particularly in eggs, milk, liver, cheese and fish.
  • the light-sensitivity of riboflavin is also one of the reasons why milk, for example, is predominantly stored and sold in light-impermeable tetrapacks or in white-coloured bottles.
  • UV absorbers for light-protection in the foodstuffs industry. It has been found, however, that the commercially available UV absorbers exhibit action only in the spectral region between about 300 and 400 nm and not in the likewise critical spectral region between 400 and 500 nm.
  • the present invention accordingly relates to a method of protecting organic material, especially from the pharmaceuticals and foodstuffs sectors, against light, wherein at least one pigment of formula
  • a UV absorber is applied to or incorporated in a carrier material and the carrier material so treated is positioned between the light source and the organic material to be protected.
